An unusual case of a saccular aneurysm of arch of aorta, masquerading as pulmonary artery branch stenosis, proved by cardiac catheterisation and angio cardiography is presented.
The accuracy of a non-invasive estimation of systolic pulmonary artery pressure in 33 patients with ventricular septal defect and/or tricuspid regurgitation, by colour guided continuous wave Doppler was evaluated. The estimated pulmonary artery pressure correlated well with values obtained at cardiac catheterization (r = 0.93). Correlation was better in cases with ventricular septal defect (r = 0.98) than in cases with tricuspid regurgitation (r = 0.87). Pulmonary artery pressure was under-estimated in cases with mild tricuspid regurgitation, probably due to eccentricity of regurgitant jet in some of these cases.
A method for functionally modifying the contour of the palatal vault of maxillary complete dentures was described. This can be achieved at the trial stage of the denture construction and incorporated in the finished denture. Alternatively, the procedure can be accomplished at the time of insertion and the palatal vault modified with self-polymerizing acrylic resin. The immediate speech achieved by the modification is much more normal and eliminates the waiting and training period after denture insertion. Because the modification of the palatal vault is achieved by the functional contact of the tongue during articulation, the tongue does not have to adapt to the presence of the denture in order to achieve "normal speech." One of the advantages of the method is the ease with which it can be performed in a clinical setting and the minimal requirement of any extra material or equipment. Moreover, no special skills are needed to achieve successful results, which can be exceptionally gratifying.
